Australian-born Israeli spy major security breach

More details have emerged about Prisoner X, Australian-born Mossad spy Ben Zygier who died in an Israeli jail while awaiting trial in 2010.

Journalists following the story say the 34-year-old Australian-trained lawyer was involved in one of Israel's most significant security breaches by embarking on an operation without his superiors' permission and in the process being duped into giving sensitive information to Mossad's enemy, Hezbollah.
